Ive un-installed all traces of 2.4. including preferences.. everything.
I then Installed 2.41.
It works fine.
BUT when i paste in my PLUGINS / MASK / FLASH folders it boots up with this error

I always back up these folders and keep them up to date religiously. This way i have a quick startup when installing a new version.
Why would i have this "failed reading prefferences on start-up"?
I hate the idea of something in there not being compatible with this version... i definately dont have the time to trouble shoot what effect .dll is doing this !
